Description

Technical Field

[0001] This utility model relates to the field of paint mist filter technology, and more specifically, to a combined dry paint mist filter. Background Technology

[0002] In related industries, painting of workpiece surfaces is often involved. During painting operations, the exhaust gases from the paint spraying process need to be treated. Dry paint mist filters use dry filter media to filter the exhaust gases emitted from outside the paint spraying room. Due to their high purification efficiency, large porosity, low filtration resistance, long service life, simple maintenance, no secondary pollution, and recyclability, they have been increasingly adopted in practical applications and have become one of the main pretreatment processes for paint spraying exhaust gas treatment. However, over time, dust can accumulate in these filters.

[0003] A search revealed a combined dry paint mist filter disclosed in document CN217613644U. In this document, folded filter paper is installed inside the device, which can achieve effective filtration. When a lot of dust adheres to the filter paper, it needs to be replaced in time. However, since the size of the filter paper is fixed, the replacement frequency of the filter paper will increase, affecting the filtration efficiency of the filter. Therefore, we propose a combined dry paint mist filter. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a combined dry paint mist filter, which solves the technical problem in existing technologies where the filter paper needs to be replaced promptly when it is covered with a lot of dust. However, since the size of the filter paper is fixed, this leads to an increased frequency of filter paper replacement, which affects the filtration efficiency of the filter.

[0005] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a combined dry paint mist filter, including a housing, an installation frame fixedly connected to the inner wall of the housing, an installation hole opened in the inner wall of the installation frame, first support plates fixedly connected to both sides of the installation frame, second support plates fixedly connected to both sides of the installation frame, a rotating shaft rotatably connected to the ends of the two second support plates, a fixing plate fixedly connected to the outer wall of the rotating shaft, a fixing rod rotatably connected to the end of the fixing plate, a locking rod fixedly connected to the end of the two fixing rods, a locking assembly installed on the outer wall of the two first support plates, the two locking rods respectively connected to the locking assembly, and a pressure plate threadedly connected to the end of the two fixing rods.

[0006] Preferably, the snap-fit ​​assembly includes two snap-fit ​​blocks, each of which is fixedly connected to a connecting rod on the side of the two snap-fit ​​blocks that is relatively far apart. The ends of the two connecting rods pass through the first support plate and extend to its outer side. The ends of the two connecting rods are fixedly connected to limit sleeves. The outer circumferential walls of the two connecting rods are fitted with first springs. The sides of the two snap-fit ​​blocks that are relatively close to each other are provided with snap-fit ​​grooves. The snap-fit ​​rods are snap-fitted into the inner walls of the two snap-fit ​​grooves respectively. The top of each snap-fit ​​block is provided with a guide groove.

[0007] Preferably, one end of the first spring is fixedly connected to the locking block, and the other end of the first spring is fixedly connected to the first support plate.

[0008] Preferably, a fixing plate is fixedly connected to the outer wall of both the first support plate and the second support plate. A sliding hole is opened on the outer wall of each fixing plate. A sliding rod is fixedly connected to the inner wall of each sliding hole. A second spring is sleeved on the outer circumference of each sliding rod. A slider is slidably connected to the inner wall of each sliding hole. The end of each sliding rod passes through the slider and is slidably connected to it.

[0009] Preferably, a pressure rod is rotatably connected between the two sliders located on the same side, and a support rod is rotatably connected between the two fixed plates located on the same side.

[0010] Preferably, one end of the second spring is fixedly connected to the fixed plate, and the other end of the second spring is fixedly connected to the slider.

[0011] The beneficial effects of this utility model are as follows:

[0012] 1. By rotating the lever, the fixing rod is rotated to rewind the filter paper. This allows the filter paper inside the mounting frame to be rolled out, and the newly unwound portion from the filter paper roll will enter the mounting frame for quick filter paper replacement.

[0013] 2. Lift the fixing rod upwards to disengage the locking rod from between the two locking blocks. Remove the pressure plate and place the filter paper roll onto one of the fixing rods. Limit one end of the filter paper roll by rotating the pressure plate. Press down the locking rod, which will press down on the guide grooves at the top of the two locking blocks. This will cause the two locking blocks to push the connecting rod to slide along the inner wall of the first support plate until the locking rod is locked inside the two locking grooves. Under the elastic force of the first spring, the two locking blocks can lock and fix the locking rod. This design facilitates quick replacement of the filter paper roll. Attached Figure Description
